SPECIFICATION forming part of Letters Patent No. 308,066, dated November 18, 1881.

Application filed April 8, 188-1. (No specimens.)

To all who/n, 71mg concern:

Be it known that I, JAMES H. Dam, of Jersey City, in the county of Hudson and State of New Jersey, have invented a new and useful Oomposition l igi g t of which the followlng 1s a speclficatloii Thisinvention relates to composition paints, such as those used in painting the bottoms of ships, dry-docks, &c. It has for its object the preservation of all surfaces to which it is ap plied, by preventing the same from becoming l'ouled, corroded, worm-eaten, or in any way destroyed by contact with water. i

I am aware that composition paints have heretofore been made and patented for the same purpose; butthe majority of these paints not only failed to accomplish what was expected of them, but they produced a very rough sui-facev'hich made their use objectionable in many cases. In this respect my composition paint differs from all others having in view the same object, inasmuch as it produces a perfectly smooth and hard surface.

To make my composition paint, take any stated amount of sulphatg pf copper and dissolve it in either hot or cold water at the proportion of one gallon of water to one pound of sulphate of copper; then d ietall' zinc preferably in the sheet form, inlh e sgutlon until the liguor on top is elear,then

filter and dry the precipitate. In another receptacle, takeanystated amount of chloride of antimony and add to it hyposul hi t e gf soda (with the aid of heat) as oiifi a a precip'itate is formed, then filter and dry this also, and mix the two precipitates in the proportion and [manner specified, with linseed,

oil, varnish, or any desirable vehicle mixed therewith, the same to be used for the purpose of preserving all surfaces that may be submerged in water or in any Waysubjected to the an ion thereof.

In testimony that I claim the foregoing improved composition paint as above described I have hereunto set my hand this 5th day of April, 1884.

JAMES H. DILKS.
